Accupro 12183093 Corner Radius End Mill 1/2 in 4 Flute Ticn

Product Description

The ACCUPRO 12183093 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1/2 inch diameter with a 0.045 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in interrupted or continuous cuts. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes smooth chip evacuation and improved surface finish. A TiCN coating provides added hardness and wear resistance for cutting ferrous and non-ferrous materials. This tool is sold as a single-end, centercutting mill, making it suitable for plunge entry and full-slot milling operations. It is used by machinists and CNC operators in job shops, aerospace, die-and-mold, and general manufacturing environments.

This end mill suits CNC machining centers and manual mills requiring a long-reach cutting tool. The 2 inch length of cut and 4 inch overall length make it appropriate for deeper pocketing and profiling operations where a standard-length tool cannot reach. The 1/2 inch shank diameter fits standard ER and CAT toolholders common in production environments. The micrograin carbide substrate supports higher surface speeds and feeds compared to standard-grade carbide, particularly useful when machining hardened steels, stainless alloys, or cast iron where edge stability is critical.

Key Features

• Solid micrograin carbide substrate for enhanced edge stability and wear resistance
• TiCN coating extends tool life in ferrous and abrasive material applications
• 0.045 inch corner radius reduces chipping and stress at the cutting edge
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry without pre-drilling
• Long-length configuration with 2 inch LOC and 4 inch OAL for deep pocket and profile work

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/2 inch shank diameter. Compatible with standard ER collet chucks, end mill holders, and shrink-fit toolholders sized for 1/2 inch shanks.

Installation Notes

This tool is installed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque tool holder fasteners per the holder manufacturer specifications. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear and degrade surface finish on a tight-tolerance corner radius tool.
